DETAILED DESCRIPTION OF THE INVENTION

[0018] Referring to FIG. 2 and FIG. 3, a dust-proof filter apparatus of the invention comprises of a body 10, at least one filter 20, and an elastic buckle assembly, which comprises at least one clasp element 31 and at least one interlocking opening 32. The body 10 consists of a rectangular upper base plate 11, a rectangular lower base plate 12, and at least one flexible connection bond 13 to form a

-shaped pleated body 10. The upper base plate 11, the lower base plate 12 and the flexible connection bond 13 form a connection end 141, an opening end 142, and a receiving space 14 disposed in the body 10. In addition, said upper base plate 11, said lower base plate 12, and said flexible connection bond 13 can be formed in one.

[0019] Referring to FIG. 4, the filter 20 is arranged in the receiving space 14 between the upper base plate 11 and the lower base plate 12. The upper base plate 11 and the lower base plate 12 have, respectively, at least one opening 15A and 15B corresponding to the location of the filter 20. Accordingly, with the opening 15A and 15B, air traveling through the filter 20 will have dust trapped in the filter 20 so that the circulating air will be cleaner. In this embodiment, the opening 15A and the opening 15B are, respectively, comprised of four rectangular openings. The filter 20 can be fixed by space frames between rectangular openings to prevent it from drop. At least one elastic buckle assembly consists of a clasp element 31 and an interlocking opening 32. The clasp element 31 and the interlocking opening 32 are, respectively, located in the surface of the opening end 142 of the body 10. The elastic buckle assembly could be located in the -surface of the opening end 142 opposite or adjacent to the connection end 141. In this embodiment, the elastic buckle assembly is located in the -surface of the opening end 142 opposite to the connection end 141. In addition, the clasp element 31 and the interlocking opening 32 are, respectively, located in the inside surface 110 of the upper base plate 11 and inside surface 120 of the lower base plate 12. The clasp element 31 is composed of 4 elastic pieces 310 to form a hollow cylinder. There is clearance 311 between adjacent elastic pieces 310. The elastic pieces 310 have one end fixed in the inside surface 110 of the upper base plate 11, the other end can be forced forward the central of the cylinder, and after force releasing, the elastic pieces 310 will spring back. The interlocking opening 32 located in the inside surface 120 of the lower base plate 12 is a ladder-shaped hole 320. The inside diameter of the fore part of the ladder-shaped hole 320 is smaller than the outside diameter of the clasp element 31. Pressing the clasp element 31, the elastic pieces 310 are forced to shrink the outside diameter of the clasp element 31, and the clasp element 31 enters into the clasp element 31 to engage with the ladder-shaped hole 320 of interlocking opening 32. Thus, the body 10 is closed and the filter 20 is fastened. Pulling the clasp element 31, the elastic pieces 310 are loosened from the ladder-shaped hole 320 of interlocking opening 32. Thus, the body 10 is open and the filter 20 is exchangeable.

[0020] In addition, the inside surface 110 of the upper base plate 11 and the inside surface 120 of the lower base plate 12 have, respectively, a rectangular inner frame 111 and a rectangular outer frame 121. The filter 20, bigger than the inner frame 111, is arranged between the inner frame 111 and the outer frame 121. When the body 10 is closed, the inner frame 111 is mounted into the outer frame 121, and the filter 20 is clamped between the inner frame 111 and the outer frame 121. When the body 10 is open, the filter 20 is exchangeable. On the top surface 112 of the upper base plate 11 has a control plate 16 which can open the body 10 conveniently. Each side of the control plate 16 has, respectively, a fast solid 18.

[0021] Referring to FIG. 5, firstly, the assembly process of the dust-proof filter apparatus is to open the body 10 to loosen the clasp element 31 from the interlocking opening 32, and arrange the upper base plate 11 and the lower base plate 12 in an included angle properly. Then, the filter 20 bigger than the inner frame 111 is placed on the outer frame 121 of the inner frame 111, and the upper base plate 11 is bended to the position of the elastic buckle assembly. The clasp element 31 is forced into engagement with the interlocking opening 32 as the clasp element 31 is pressed. Thus, the body 10 is closed and the filter 20 is fastened. The assembly process is convenient. The dust-proof apparatus can install in the inlet of a conditioner or a cooling system to filter particles.

[0022] Referring to FIG. 6, a sliding way 41 is placed into a base 40 of the conditioner or the cooling system. The top surface 112 of the body 10 of the dust-proof apparatus further comprises a push-pull plank 17 to push or pull the dust-proof filter apparatus conveniently. As shown in FIG. 7 and FIG. 8, by pushing the push-pull plank 17, the dust-proof filter apparatus is inserted into the sliding way 41, so that the dust-proof filter apparatus is mounted into the sliding way 41. The fast solid 18 is inserted into a slot (not shown) in the sliding way 41 in order to fasten the dust-proof filter apparatus. Air traveling through the opening 15A of the upper base plate 11, the filter 20 has dust trapped in the filter 20 so that the circulating air will be cleaner and go through the opening of the lower base plate 12 into the system for use. The fast assembly process for the dust-proof filter apparatus is convenient. As exchanging the filter for washing or cleaning, just pull the push-pull plank 17 to pull out the dust-proof filter apparatus. Then, pulling the clasp element 31, the elastic pieces 310 are loosened from the ladder-shaped hole 320 of interlocking opening 32. Thus, the body 10 is open and the filter 20 is exchangeable. In accordance to the method, it's convenient to take the filter 20 apart from the dust-proof filter apparatus.
